  • Sustainability In Your Ear: The XPRIZE Wildfire Competition Heats Up

    Sustainability In Your Ear: The XPRIZE Wildfire Competition Heats Up
    2026/03/16
    Every wildfire starts small. The problem is that by the time most are detected, minutes have already passed and, under increasingly common conditions driven by a warming climate, a fire can grow beyond any tanker truck's capacity to contain. The gap between ignition and coordinated response currently averages around 40 minutes. Firefighters have long understood the math: a spoonful of water in the first second, a bucket in the first minute, a truckload in the first hour. The XPRIZE Wildfire competition is an $11 million global effort to prove that autonomous systems, including AI-enabled drones, ground-based sensor networks, and space-based detection platforms, can collapse that window to 10 minutes. Our guest is Andrea Santy, who leads the program. She came to XPRIZE after nearly two decades at the World Wildlife Fund, where she watched conservation projects fall to wildfire. That experience sharpened her understanding of the stakes: wildfires are now the leading driver of deforestation globally, having surpassed agriculture. In places like the Amazon, the Congo Basin, and parts of tropical East Asia, a single fire can eliminate species found nowhere else on Earth. In cities, it can destroy entire neighborhoods in hours. On January 7, 2025, Santa Ana winds drove flames through Pacific Palisades and Altadena, destroying more than 16,000 structures, killing 30 people, displacing 180,000 residents, and generating between $76 billion and $130 billion in total economic losses from a single event. Annual U.S. wildfire costs, when healthcare, lost productivity, ecosystem damage, and rebuilding are included, are estimated between $394 billion and $893 billion. XPRIZE announced the five autonomous wildfire response finalists just over a year after the LA fires: Anduril, deploying its Lattice AI platform with autonomous fire sentry towers and Ghost X drones; Dryad, running solar-powered mesh sensor networks that detect fires at the smoldering stage; Fire Swarm Solutions, coordinating heavy-lift drone swarms that can deliver 100 gallons of water autonomously; Data Blanket, building rapidly deployable drone swarms for real-time perimeter mapping and suppression; and Wildfire Quest, a team of high school students from Valley Christian High School in San Jose who used multi-sensor triangulation to locate fires that can't be seen from monitoring positions, solving the literal over-the-hill problem that any fire detection system faces.The conversation covers what the finalists demonstrated during semi-final trials at 40-mile-per-hour winds, why the decoy fire requirement — distinguishing a wildfire from a barbecue, a pile burn, or a flapping tarp — is one of the hardest AI classification problems in the competition, and how autonomous systems would integrate with existing incident command structures. Santy is direct about where progress is lagging: the testing is ahead of the regulations. Autonomous drones operating beyond visual line of sight and coordinating with manned aircraft in active fire emergencies require FAA frameworks that don't yet exist at the necessary scale. There's also the deeper ecological tension — the growing scientific consensus that many fire-adapted landscapes need more fire, not less, and that indigenous fire stewardship practices developed over millennia have a place alongside autonomous suppression technology. One XPRIZE finalist is already working with an indigenous community in Canada to pilot their heavy-lift drone system in a remote area where that community is exploring how the technology fits their land management approach. Meanwhile, the Trump administration's FY 2026 budget proposes eliminating Forest Service state fire capacity grants, cutting vegetation and watershed management programs by 30%, and zeroing out $300 million in forest research funding — maintaining suppression spending while gutting the prevention and detection infrastructure that could reduce what there is to suppress. The engineering, Santy says, has arrived. Whether the institutions can move at the speed the crisis demands is the harder question.You can learn more about XPRIZE Wildfire and follow the finalists at xprize.org/competitions/wildfire.

  • The MooBlue Team Keeps The Beef, Without The Burp

    The MooBlue Team Keeps The Beef, Without The Burp
    2026/03/09
    Cattle are one of the most consequential climate problems hiding in plain sight on the dinner table. Livestock are responsible for roughly 14.5% of global greenhouse gas emissions, according to the United Nations Food and Agriculture Organization, and cattle alone account for about 65% of that sector's output. Most of it doesn't come from manure or land use — it comes from inside the cow. Approximately one billion cattle on the planet burp around 3.7 gigatons of CO₂-equivalent emissions annually, more than the aviation and shipping industries combined.

    A growing number of researchers and companies are focused on a deceptively simple approach: change what a cow eats. A red seaweed called Asparagopsis taxiformis contains bromoform, a compound that blocks the enzymes used by methane-producing microbes in the rumen. Today's guests didn't learn about this from a graduate seminar. They're high school students, and they built an idea for their first company around it. Every January, I judge a Shark Tank-style competition that caps a month-long entrepreneurship program at the Bush School in Seattle. This year, a pitch by three students stopped me cold. Zara, Ellie, and Kai Aizawa are the co-founders of MooBlue, whose tagline — Cut the burp, keep the beef — got a laugh, but whose business concept is entirely serious. Kai is heading to Haverford College in the fall. Zara and Ellie are still freshmen.

    MooBlue proposes harvesting Asparagopsis from the Mediterranean, where it is an invasive species currently harming marine ecosystems, processing it into an oil-based feed additive and building a certification and labeling system so consumers can identify beef and dairy products raised using reduced-methane feeds. What struck me wasn't just the idea. It was the depth of the research: from the biochemistry of rumen fermentation to the intellectual property landscape to a two-segment go-to-market strategy targeting large corporate operations and family farms. They covered the competitive white space, the supply chain, the financial incentives for farmers, and the consumer psychology of premium labeling, all with the ease of people who had genuinely internalized what they were talking about.

    The conversation shows that the internet has exploded ceiling of what a curious teenager can discover. When Zara, Ellie, and Kai needed to understand the biochemistry of enteric fermentation, they found recent, peer-reviewed research. When I was their age, those journals would have been available only at a university library, if they existed at all. Today, a high school freshman in Seattle can find a paper out of, understand the biochemistry well enough to explain it clearly, and build a company around the discovery. That changes what a generation can imagine. And it may change what we can collectively accomplish.You can learn more about the Bush School's entrepreneurship program at bush.edu.

  • The Forest Stewardship Councils' Path to a Circular Bio-based Future with Loa Dalgaard Worm

    The Forest Stewardship Councils' Path to a Circular Bio-based Future with Loa Dalgaard Worm
    2026/03/02
    Forests are vital for people everywhere. They cover about 4.14 billion hectares, roughly a third of the world’s land, and store 714 gigatons of carbon. They also support 80% of land-based biodiversity. However, we are losing 11 million hectares each year to deforestation, and the World Bank expects demand for forest-based products to rise by 400% by 2050. Many industries, from construction to textiles and automotive, are turning to wood fiber to replace fossil-based materials. Yet, a 2023 Circularity Gap Report found that over 90% of materials entering the global economy come from nature and end up in landfills. This approach is not sustainable. If we do not change how we use and reuse fiber, forests will be depleted faster than they can recover. Today’s guest, Loa Dalgaard Worm, leads the Forest Stewardship Council’s Circularity Hub. This innovation team, launched in 2023, is updating a certification system that was originally designed for a linear economy 30 years ago. Her team is working to add circular business models, like take-back, repair, and leasing, to FSC’s chain-of-custody standard, which already includes 70,000 companies worldwide. They are also creating a framework to certify agricultural leftovers, such as wheat straw, rice husks, and coffee chaff, as alternative fibers for pulp-based products. This helps reduce the need for new forest fiber.Loa’s boldest idea is a royalty system that would pay forest owners a small fee each time fiber from their forest is reused or recycled into a new product. Currently, forest owners are paid only once, when they harvest a tree, and do not receive ongoing rewards for protecting ecosystems, conserving biodiversity, or supporting communities. Companies buying recycled fiber would pay for verified origin data, which they increasingly need to meet the EU Deforestation Regulation and other international standards. The pieces for this plan are coming together. FSC already runs FSC Trace, a blockchain-based traceability platform, and works with World Forest ID on isotope testing that can identify a fiber’s origin within about 15 kilometers. They also partner with esri to improve earth observation capabilities. “We used to be able to do this,” Loa says about circularity, pointing out that remembering old habits, not just inventing new ones, is key to sustainability. “Our parents knew how to repair things. My grandmother knew how to mend all of her clothes.” FSC’s circularity work is focused on rebuilding the systems needed to help us relearn how to reuse and repair on a large scale. Loa hopes to test the royalty system within two years and present it to FSC’s General Assembly for discussion by 2029. The big question is whether institutions and markets will move quickly enough to protect forests.
